Purchasing and installing a prefabricated or prefab home is an exciting process, but it does require advance planning to ensure everything goes smoothly. Here is a recommended 6-month checklist developed in consultation with experts at Lida Group, a leading global prefab home builder, to optimize your timeline:

6 months out:
Initial property site evaluation

– Select your property location if you don’t already own land. Consider soil composition, drainage, flood zones, views etc. Hire a surveyor for mapping.

– Obtain construction permits from your local planning authority, which can take 4-6 weeks. Permits will specify zoning, setbacks, utility connections allowed.

– Arrange or test property utilities – electricity, water, septic/sewer, natural gas, internet/phone. Ensure capacity for a home. Temporary construction utilities also needed.

Prefab home design planning

– Consult Lida Group or another reputable prefab supplier about home models, customization options, schedules and budgets to match your needs and property.

– Receive preliminary floor plans, elevation sketches and renderings from the supplier to visualize your prefab design.

– Obtain multiple quotes for material/feature upgrades before finalizing blueprint specifications. Factors impacting build budget include size, foundation type, custom millwork.

Site preparation

– Hire an excavation contractor 4 months ahead of the projected delivery date to clear vegetation, level the site, dig foundation trenches and install septic/drainage lines before prefab installation.

– Contractors should also be identified for additional tasks like driveways, landscaping, decks that will coincide with house installation. Schedule accordingly.

Order long lead materials

– Consider special-order windows, doors, appliances or fixtures that may require extra manufacturing lead times. Place orders promptly to avoid delays.

5 months out:
Finalize home design plans

– Meet with the prefab supplier’s designer to finalize all exterior/interior design elements, cabinets, colors, fixtures etc based on preliminary concepts.

– Generate and approve final engineering blueprints incorporating all structural, electrical and mechanical system specifications before production.

– Order any custom designed fixtures or fittings through specialized contractors/fabricators.

Site work commences

– Work with the excavation contractor to complete foundation/slab preparation, underground utilities and grading on schedule for installing prefab sections.

– Obtain final site inspection approval from the local planning authority before transporting prefab modules. This verifies property/site readiness.

Order production

– Submit finalized plans and 20-30% down payment as per contract terms to trigger manufacturing of your prefab home sections at the supplier’s factory.

– Production time depends on home/factory size but averages 6-12 weeks. Sections are fabricated concurrently on an assembly line.

Mortgage pre-approval

– Consult your bank or loan officer to obtain a pre-approval letter verifying your budget. Most prefab builders require this before production commences.

4 months out:
Supply chain coordination

– Liaise with the prefab supplier to coordinate delivery logistics of modules 4-6 weeks in advance based on estimated completion schedules.

– Supplier will arrange specialized transport equipment like trailer beds, pilot cars, off-loading cranes as required. Overweight/oversize permits must be obtained.

Scheduling site installation

– Coordinate preferred installation dates with the prefab supplier and general contractor for optimal weather windows. Rain/storms can delay outdoor work.

– Book related tradespeople for tasks during/after installation like finishing, electrical hookups, plumbing connections, drywall etc.

Site preparation wrap-up

– Inspect foundation/slab/utilities with the general contractor and make necessary fixes before prefab delivery. Proper compaction and finish grading are critical.

– Demarcate overhang easements, lay base materials like gravel in high-traffic areas for post-assembly surfacing and landscaping.

3 months out:
Structure installation prep

– Cleary mark property/foundation lines based on engineering plans to guide module placement in the field. Align securely.

– Assemble temporary structures like covered work areas/storage sheds and facilities for trade crew comfort onsite.

– Stockpile tools, hardware, lighting, generator power supplies etc for smooth installation flow over consecutive days.

Utility connections

– Arrange pre-connection inspections for electrical, plumbing, HVAC hookups with relevant authorities to verify code compliance.

– Have trade contractors standby to make final internal connections once modules are joined together properly.

Mortgage finalization

– Apply for and finalize your construction loan or standard mortgage. Schedule inspection/appraisal if needed. Funds must be accessible on delivery date.

2 months out:\
Order building supplies

– Procure additional fasteners, sealants, trim, flooring materials required to finish joining structural elements delivered by the prefab supplier.

– Consider delivery timing to avoid postponing installation. Storage will be limited onsite.

Install infrastructure

– Lay underground plumbing, electrical lines connecting internal systems to property services before modules arrive.

– Erect deck/porch supports, driveways/walkways based on engineering plans to receive prefab components.

1 month out:\
Inspection readiness

– Conduct pre-installation site walks with general contractor, builder and authorized inspectors to ensure property/foundation preparedness.

– Supplier will also inspect modules before shipping. Address any remedial work required.

Order landscaping

– Procure sod, plants, trees and hardscaping materials for post-installation beautification agreed in design plan. Consider seasonal planting schedules.

Schedule move-in

– Arrange utility connections, request final inspections, procure any occupancy permits. Plan fridge/furniture delivery, cleaning, landscaping around projected assembly completion dates.
